RADIATOR FiledMarch 30, 1929 Patented `lune 16, 1931 .smiles RADIATOR o Appncation mea Maren 3o, 1929. serial Natalee-7.

The present invention has for its object to produce a radiator for heating air thatV shall be light and of simple construction;

that shall be eflioient in operation, l'not only 5 in the sense of efciently interchanging heat energy, but also in the sense of reducing the resistance to the free flow of air past the heating elements; and that shall produce a more elfective distribution of the heat in a room or space wherein the radiator is situated, than has heretoforebeen possible through the use of radiators alone.

In carrying out my invention I so construct the radiator that there'gwill be. air passages extending up from' the botto1n` of the same and out through the side; the passages being gradually curved so that the air flowing up through the same isnot required to change its course abruptly. Furthermore', the pas- 20 sages become progressively enlarged,'to compensate for the natural expansion of the air as its temperature is rising during its passage through the'radiator; thus avoiding a choking effect and reducing the resistance to a minimum. When such a radiator is placed in a room, the heated air is not travelling in the vertical direction asit leaves the radiator, but it is moving approximately horizontally; thus producing a higher temperature kin the 0 zones occupied by Vthe people in the room than that in the case of an vordinary radiator. In other'words, a highly desirable distribuo tion of theheated air is secured without the use of fans or other means acting on the air after it leaves the radiator. A radiator of this kind is particularly adapted for situa tions where it must be placed within a wall, since lit will function precisely and deliver into the roomthe same amount of heated air, flowing at the same speed and inY the same direction, as though the radiator were standing out in the room.

The various features of novelty whereby my invention is characterized will herein-L after lbe pointed out with particularity in the claims; but, for a kfull understanding of my invention and of its objects and advantages reference may be had to the following detailed description taken in connection with the accompanying drawings, wherein:

Figures l and 2 are respectively a frontand a side elevation of a radiator constructed in accordance with-theprescnt invention; Fig. 3 1s a section on line 3-3 of Fig. l, on a lsomewhat'larger scale thefins being omitted; Fig. 4r is a front view, on a still larger scale, of a fragment of the radiator at one uppeiI corner; Fig. 5 is a section on line 5-5 of Fig. 4; and F ig. 6 is asection taken approximately on line 6 6 of Fig. 5. l

Referring to the drawings, l and 2 representtwo hollow heads connected together by a series of comparatively thin hollow Awalls of ywhich live, indicated. at 3, 4, 5, 6

and 7 are shown.` The hollow walls connect the interiors 'of the twoy heads together. If hot water,for example, is allowed to flow into the head1 through pipe 8, for example, and out from the vhead 2 through a pipe 9, it will pass from the head l to the head 2 through the several hollow walls. The hollow walls are arranged one in front of the other,corresponding ends terminating short of theplane of the bottoms of the rheads if there are no legs or other means to support the device in suchV a manner that air may enter into the spaces between the lower ends of the walls. The hollow walls extend upwardly and forwardly, being progressively, preferably gradually, curved from one end tothe other. The curvatures are such that the walls div-ertgradually from each other asthey rise and bend forwardly, thus causing each of thespaces bounded on two sides by two ofysuch walls to increase gradually in cross-sectionalarea. Therefore, the spaces between the hollow walls being passages for 'the air that is being heated, the air entering Ythe .passages at the bottom of the radiator is free to expand naturally as it rises and .has its temperature increased, so that there will be no back pressure in the passages tending to choke back the flow of air. n

The radiator being set in a room, for example, and hot water beingsuppli'ed to the n radiator in any/usual or suitable 'marinera the` air will Vmove upwardly through the air passages and will be discharged in a heated 'condition invv an almost horizontal direction;

the result being that the heated air moves laterally into the room and heats the lower and intermediate regions, instead of rising straight to the ceiling or roof from the radiator.

The surfaces of the hollow walls, of themselves, will not interchange sufficient heat, and therefore I provide each air space with numerous heat interchanging tins whose combined superficial areas will be very great. In the arrangement shown, I have placed in each of the air passages a large number of thin parallel vanes each extending entirely across the passage and engaging at its edges with the two corresponding hollow walls; the vanes preferably standing in vertical planes. Each vane is preferably provided with flanges ll extending laterally therefrom at its two long edges, the ilanges lying in intimate contact with the hollow walls and insuring that heat from the hollow walls will be carried into the vanes. The flanges on the Vanes also serve as spacers to hold the vanes apart, thus greatly facilitating the assembling of the vanes in one of the passages; the vanes being simply dropped into the passages while one el' the headers is disconnected anc, through their flanges, being self-spacing.

The parts of the radiator may be made of any suitable material as, for example, sheet copper, so that a large amount of air can be eliiciently heated and distributed by a comparatively small and light radiator.

`While I have illustrated and described with particularity only a single preferred form of my invention, I do not desire to be limited to the exact structural details Ythus illustrated and described; but intend to cover all forms and arrangementsV which como within the definitions ot my invention constituting the appended claims.

I claim l. A radiator having long air passages extending through the same and increasing progressively from their inlet ends toward their outlet ends, a series of parallel longitudinal individual partitions extending through and fitting in each passage, and flanges at the long edges of each partition lying iat against the adjacent bounding walls of the passage.

2. In a radiator, two separated hollow heads, comparatively thin hollow walls extending between the heads and connecting their interiors together, said walls rising from the bottom ot the radiator and curving laterally to one of the sides, and the walls diverging from their lower ends toward the top to produce between them open-ended air passages increasing gradually in cross-sectional area from their lowerto their upper ends.

3. A radiator comprising a series of long wide heat-emitting elements arranged one behind the other and extending in smooth curves from the bottom of the radiator upwardly and to one side of the latter and producing a plurality of open-ended air passages, the curvature of each of said elements being less sharp than that of the elements in front of the same to cause said air passages to increase in cross sectional area from the lower ends upwardly.
